APPARATUS FOR COOKING COTTON-SEED MEAL.

SPECIFICATION forming part of Letters Patent No. 545,271, dated August27, 1895.

Application filed March '7, 1894. Serial No. 502,752. (No model.)

To aZZ wit-0711, it may concern:

Be it known that we, BENJAMIN DABNEY, residing at Bonham, in the countyof Fannin, and WILLIAM I. YOPP, residing at Houston, in the county ofHarris, State of Texas, citizens of the United States, have inventedcertain new and useful Improvements in Apparatus for Cooking Cotton-SeedMeal; and we do hereby declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same, referencebeing had to the accompanying drawings, and to letters of referencemarked thereon, which form a partof this specification.

The object of the present invention is to provide an apparatus forcooking or treating cotton-seed meal, so as to obtain therefrom themaximum amount of oil in the subsequent treatment of the meal for itsextraction; and the invention embodies an apparatus which admits of therequisite amount of moisture being supplied to the meal when there is adeficiency of natural moisture in the same and for the subsequentevaporation of any excess of moisture, together with the gradual andcontinuous feed of the meal into and through a water-bath, whereby thedevelopment of steam in contact with the meal itself takes placegradually and injury to the meal by reason of the direct application ofhot live steam is avoided.

The invention consists of a boiler or heater and of certain details ofconstruction, all of which willbe fully described, and then pointed outin the claims.

In the accompanying drawings, Figure l is a side elevatiompartlyinsection, of an apparatus adapted to practice this process. Fig. 2 is asectional view of the boiler on the line a" w, and Fig. 3 is a likesection on the line 1/ y.

A is an ordinary cylindrical tubular steamboiler, a indicating theiire-tubes.

Centrally placed within the boiler and below the water-line thereofthere is a pair of conveyor-tubes B B, one above the other, and eachprovided with a screw conveyor 1) b, supported on end bearings. Theseconveyortubes and conveyors extend back beyond the end of the boiler andthrough the furnacewall 0 G and respectively receive the raw meal anddischarge the cooked meal at their outer ends; A power connection isshown at b for driving the conveyors. At the inner end the twoconveyor-fines are joined by the downfiue 19 one side of which is formedby the plate or partition b, which is provided with the bearings 12 bfor the inner ends of the screw conveyors. These bearings are closed inand protected from the hot gases and products of combustion by the irondoor If, and access can be had to them for oiling, 860., through theflue-cleaning door in the head of the boiler and this inner door 12 Atthe opposite end of the boiler the conveyor-fines where they leave theboiler proper and are continued across the fire-space to the furnace-Wall 0 are protected by a. continuation A of the boiler proper, whichforms a neck incasing the conveyor-tubes and a water-jacket for them,protecting them and the metal from the effect of too high a temperature.A receiver or feed-chute for the meal to the first conveyer-tube isshown-at E, and the same has a water-pipe c, with valve 6, by means or"which the requisite amountof water is sprayed into or added to the mealas the same passes down the feeding-chute E into the machine.

F is a conveyor for feeding the meal to the receiving-chute E from anypreliminary machine for treating the meal or source of supply, or thefeedingchute E may be a supplyhopper into which the meal is dumped. Thelower conveyor-tube B discharges the meal into a steam-jacketed drum orreceptacle G through the connecting-pipe g, and any excess of moisturecarried by the meal after it thus leaves the cooker is evaporated off inthis receptacle. This drum is provided with a revolving rake G, whichdistributes the meal on the floor of the drum and at the same time turnsit over and works it around to the discharge-opening g. G is an outletpipe or opening for the escape of moisture or steam, with a damper orslide to regulate the same. The discharge-hole g may have a slide g forpartially closing the same to fit the requirements of the case.

From what has preceded, the operation of the apparatus will be easilyunderstood.
